They don't make them any more. Some compacts have optional clip on electronic viewfinders but they tend to be the top end of the market.

I also found this annoying a few years ago when I went to replace a mid range compact (I think it was a Casio) and discovered there wasn't a single non-high end compact camera on the market that had any sort of viewfinder. I guess these days people don't want them...

Something you might want to consider, and I mention this only as an option, is getting an older mirrorless interchangeable lens camera that has an electronic viewfinder, something like a Panasonic G1 or G3 or a Samsung NX 10 or 11 (I bought a NX10 and now have an NX20, but I've recommended the panasonics to friends and they're happy with them). You can get body + kit lens for any of these on ebay for less than 200 pounds, and if you go with the panasonic you can find reasonably priced zooms that will cover a good range.

The only downside is this is not as small as a compact, but you gain much better ergonomics and better image quality too.
